Hi, We have nodes A and B as part of one XtraDB cluster and nodes C and D as part of second XtraDB cluster We are trying to setup async replication between A and C, thus replicating data between the 2 clusters. This configuration seems to be working. How should we deal with the following scenario: 1. Node A goes down. Is there a way to automatically repoint - Node C to replicate from Node B instead of Node A? - Node B to replicate from Node C? Please note that async replication was never setup on nodes B and D. 1. I have also tried following configuration: - 2 XtraDB clusters each having 2 nodes and an arbitrator. Nodes A and B for PXC1 and nodes C and D for PXC2. # GTID related parameters are setup in config files for XtraDB clusters. gtid-mode=on enforce-gtid-consistency=true - async replication between Nodes A and C but the master is not set to the host name directly. We are using instead virtual names. For example: - Virt\_PXC1 name is pointing to Node A when node A is up and to Node B when node A is down. - Virt\_PXC2 name is pointing to Node C when node D is up and to Node D when node C is down. This way the async replication between node A and node C is setup using Virt\_PXC1 and Virt\_PXC2. Async replication is set with master\_auto\_position = 1. Despite having master\_auto\_position = 1 this configuration is still not working. Any input on the above 2 scenarios? How is it usually handled async replication between 2 XtraDB clusters? Thank you, Liviu
